The FM transmitter or FM modulator is a simple and inexpensive way to improve the car's audio system. It is a compact device capable of reading the sound from a memory card, a USB storage device, or an MP3 player, and passing it to any radio set up on the same frequency as the FM transmitter. The radius of the transmitter is usually 5 to 10 meters. Who needs a FM transmitter?
Who needs a FM transmitter?
The FM transmitter will be useful in situations where it is necessary to increase the functionality of automation, but there is no desire or possibility to change it. This may be related to an irregular mounting size of the magnetol or, for example, the use of the display of the magnets by other systems of the car-the vehicle computer or climate control. Often a regular car magnet has control buttons on the handlebar or near the handlebar, which will not work if the magnet is replaced.
The transmitter will also help in the event of a failure of the CD player.
What are they like?
FM-transmitters can be divided into two types: automotive and universal. The vehicle is connected to a 12 or 24 volt outlet or to the sprinkler receptacle and fed from the vehicle's side network. Universal transmitters connect to an MP3 player or other audio device and feed on its battery.
There are many reasons to keep the regular audio system: this is control on handlebars, and data from the onboard computer on the display
There are also transmitters designed to connect to the players of a certain manufacturer or even a model, as well as a transmitter with additional functions such as the connection of a mobile phone via Bluetooth and the ability to accept or reject a call by buttons located on the transmitter.
Advantages and disadvantages of the device
The main advantages of the device are ease of use, low cost and high functionality.
The deficiencies of any transmitter can be attributed to a rather weak transmitter: in the big city there are regular noise during playback, the transmitter can cut the connection.
How to select a model
The FM-transmitter is an inexpensive device, prices start at 300 rubles for models of unknown Chinese manufacturers, but there is a sense not to save and buy a model more expensive from a more well-known manufacturer. In a situation with a transmitter, the price usually determines the quality.
The transmitter is significantly cheaper than the new magnet-from 300 rubles to 2-$3 thousand for more "birthday".
It is also worth to ask the seller whether the transmitter can distinguish between folders and files and start playing from the file that it ended before, or play it every time from the first file in the playlist.
The transmitter may be monochrome or colored, large or small. The display is the last thing to pay attention to when selecting a device. The small dimensions of the transmitter and its location do not allow the display to be used for navigation on the playlist during the movement, and during the stop, it is hard to see the text and symbols.
Qualitative road transporters are usually equipped with additional safety fuses. He'll save the device from the spikes in the vehicle's side network.
Most of the transmitter is fitted with a control panel. The main value of the remote is convenient buttons. Typically, the transmitter itself is very small and it is not convenient to press them because the transmitter is adjusted at the angle of inclination and is moved up or down each time it is pressed. It has to be kept by and distracted from driving.
In summary
The transmitter will not be suitable for those who appreciate the crystal quality of sound, but for all the rest will be an excellent alternative to the costly replacement of the magnetol. The sound quality produced by the use of FM-transmitter is comparable to the sound produced by listening to the radio. The purity of the sound depends mainly on the power of the transmitter transmitter and the "load" of the FM range.
